It helps keep the cab air clean, prevents debris from damaging the blower motor and evaporator core, and maintains good airflow for defrost and A/C. Replace it when you notice reduced airflow, musty odors, or foggy windows — typically every 12,000 to 15,000 miles. The filter is a direct-fit panel style, commonly cross-referenced with WIX 24479 and used on a wide range of light-duty vehicles as well as select Kenworth and Peterbilt truck models.
